"But he is very young. I hope he can improve very fast. For the moment, he's not Courtois, of course. But I'm very happy to have him and Mateo Kovacic coming in.

"The Courtois situation was clear. He wanted to go to Madrid. So we lost maybe one of the most important goalkeepers in the world. But we bought a young goalkeeper, I think one of the most important among young goalkeepers in Europe, so I'm really happy.

"I’m happy, too with Kovacic because he has the characteristics for us. He is a very technical player and he likes to play between the lines. For us, that could be very important."
